SHOCK-ABSORBING HEEL.

Specification o f Letters Patent. Patented Jan. 27, 1920.

Application filed April 30, 1919. "Serial No. 293,844.

To aZZ who-m t may concern:

Be it known that l, W ILLIAMV. BROWN, afcitizen oi' the United States, residing at Arkansas City, in the county of Cowley and State ot' Kansas, have invented certain new and useful Improvements in Shock-Absorbing Heels, ot' which the following is a speciiication, reference being had therein to the accompanying drawings.

This invention relates to a shock absorbing heel, and has for its obj ect the construction of an efcient and comparatively simple heel that employs springs between the outer and the inner section, arranged, 'in combination with other parts, to produce very satisfactory results.

With this and other objects in view my invention comprises certain combinations and arrangements of parts as are fully illustrated in the accompanying drawing and will be specifically described in the following specilication and clearly pointed out in the appended claims.

In the drawing:

Figure 1 is a view in side elevation of the shoe, showing in longitudinal section my improved heel applied thereto.

Fig. 2 is an interior view of the outer portion of my improved heel.

Fig. 3 is an interior view of the inner or upper portion o'f the heel.

Fig. 4 is a sectional view taken on the line 4 4 of Fig. 1, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates a shoe that is provided with the usual heel portion 2., and to the heel portion 2 is secured the inner or auxiliary section 3 of my improved heel. The outer or primary, movable section 4 of the heel, comprises a metal casing that is provided with a central threaded boss 5, into which boss is threaded the screw 6, which screw has its head 7 positioned in the enlarged socket 8, formed in the central portion of the heel 2 and the auxiliary section 3, Fig. 1. On the outer face of the casing or primary, movable section 4, is a layer 9, of material such as leather or the like, and this layer or covering 9, upon the outer face of the primary section or casing 4, is held upon the casing or section by screws 10.

A hollow inner casing 11 is provided with horizontal flanges 12 that rests against the heel portion 2 oi the shoe, and the upper end 4u of the primary casing or section 4,

is positioned within the inner casing 11 (Figs. 1 and 4) and has a sliding action within said casing.

interposed between the outer `casing or section 4 and the inner section 3,A are a plurality of coiled springs 13; these springs 13 prevent the wearer of the shoe from receiving a shock as he walks, the springs taking up the jar by pressure on the heel, and in the event an undue lamount of strain is placed upon the spring 13, by the wearer jumping from a height, the rear roundedoff portion 14 of the inner section 3 will act as a brake and will relieve a certain amount of the shock or strain that is too great for the spring 13, allowing the linner edge 4, at the back oit' the primary casing section 4, to ride upon the beveled face 14, and jam the upper edge 4a, at the rear, against the inner casing 11, as shown in Fig. 1, and thereby relieve any undue strain that may occur at unusual times. Further, by the upper edge 4a riding' against the beveled edge 14, it directs the casing 4 into tight engagement with the front edge of the inner section 3, by reason of a slight binding action, although it is appreciated that such action will be only of a small degree since bolt G will not permit of a big movement, but there is a sufficient movement to act in the nature of a brake if the pressure on the heel is too great for the springs 13 to absorb.

What I claim is:

1. A device of the class described, comprising a heel portion, an auxiliary section secured to said heel portion, an inner casing provided with a horizontal ange, said iange secured between the auxiliary section and the heel portion against the heel nortion, said auxiliary section being spaced at its outer edges from the inner casing, said auxiliary section being provided at its rear with a curved face contiguous to the inner tace of the rear portion of the inner casing, a primary casing having its inner edge positioned within the inner casing. means movably securing the primary casing upon the inner section, and springs interposed between the auxiliary section and the primary casing.' said inner edge of the primary casing being adapted to ride over the curved face at the rear of the auxiliarv section and moved into engagement with the inner face of the rear portion of the inner casing, crowding the inner face of the primary casing against the front edge of the auxiliary section, whereby an auxiliary Shockabsorbing action is accomplished in addition to the shock-absorbing action of said springs.

2. A device of the class described, comprising a heel portion, an auxiliary portion secured to said heel portion, an inner casing having a flange secured against the heel portion, the auxiliary portion having a part extending over said flange of the inner casing, said extending portion being beveled or curved under said flange of the inner casing, van outer casing positioned over the auxiliary portion, means movably attaching said outer casing to said auxiliary portion, and yielding means interposed between said outer casing and said auxiliary portion, and said upper casing adapted to have its inner edge bear against the beveled portion and ride over the same, under the flange of the inner casing, whereby an additional braking action is secured upon the inner portion when undue strain is brought to bear upon the outer casing, in addition to the action oi the yielding means.

In testimony whereofl hereunto allix my signature.

`WILLIAM W. BROWN.
